Kyōka Suigetsu and Sharingan

In the following days, Kakashi fell into a desperate situation where his inspiration was exhausted.

Even if he was called copy ninja Kakashi, there would be a time when he was exhausted.

Under the pressure of Naruto, he continued to teach the known wind attribute Ninjutsu.

Some of them were of little value to Ninjutsu, while some were extremely powerful.

No matter what Ninjutsu was, Naruto could learn it in a very short time.

Although the proficiency and stability were relatively weak, these could be made up for by the later practice.

Finally, under Naruto's inquiry again, Kakashi's mouth under the mask twitched slightly, and the dead fish eyes showed helplessness: "There is another Ninjutsu who is suitable for you. Do you want to learn?"

"Learn, why not learn? What Ninjutsu?"

"Sennen Goroshi."

From then on, Naruto no longer asked Kakashi to learn Ninjutsu.

Kakashi expressed his regret.

Just imagine, with a gentle smile on his face, Naruto first used Kyōka Suigetsu to control the vision of the enemy and then used Shunpo to come behind the enemy. After a series of complicated seals, he used Sennen Goroshi to enter the enemy's most warm and fragile part.

This was the ultimate Ninjutsu that was tailored for his Kekkei Genkai.

Unfortunately.

He could not see this scene.

...

In the training ground.

Following Naruto's request, Sasuke prepared to activate Sharingan to crack Kyōka Suigetsu.

"I'll have to trouble you this time, Sasuke." Naruto still had his signature gentle smile.

On the other side, Sasuke had a smelly fart on his face, "Hmph, come at me. In front of my eyes, all Genjutsu is useless."

Sharingan had a strong resistance to Genjutsu, so Sasuke was confident that Naruto's Kekkei Genkai would be useless in front of him.

"Then, be careful. Break, Kyōka Suigetsu." The Kyōka Suigetsu in Naruto's hand fell to the ground, shattered into pieces, and disappeared from sight.

Sasuke only felt his vision blur, and the world seemed to ripple.

"This is the Kyōka Suigetsu I was hit with before, right?" Sasuke took a deep breath. He was not in a hurry to open Sharingan. He first used his normal eyes to feel the Genjutsu of Naruto.

"The refraction of water, mist, light and other natural elements can control the vision of the other party, resulting in a visual deviation," Sasuke remembered Kyōka Suigetsu's ability and was always on guard.

"This way." Naruto punched Sasuke.

The wind created by the fist caused Sasuke's eyes to widen. "It's right in front of me!" He swung his fist and felt lonely. However, his right shoulder felt pain and he was immediately pushed back several steps.

However, Naruto withdrew his strength at the critical moment and did not cause Sasuke too much pain.

"That's impossible! Even if there is a deviation in vision, the fist wind is indeed coming right at us?" Sasuke asked in confusion.

"The illusion is not as simple as you think." Naruto walked up to Sasuke and waved his hand in front of his eyes.

A gentle breeze blew and ripples appeared in front of his eyes. In Sasuke's line of sight, Naruto's palm fell straight down on his face. He subconsciously took a step back.

"A person's brain is very wonderful." Naruto put away the ball and explained with a smile, "In your opinion, my Kekkei Genkai is fake Genjutsu's illusion. By changing the surrounding environment to create an illusion effect, to a certain extent, it is actually not Genjutsu."

Sasuke nodded. "The real Genjutsu should be able to affect all senses."

Naruto shook his head. "Wrong."

"Wrong? Could it be that Kyōka Suigetsu can affect other senses?" Sasuke had a doubtful look on his face.

"This is your misconception." Naruto continued,

The illusion comes from two possibilities. One is the visual system. When the visual system appears in a blind spot, or you are a person who is weak in color and blind, the information you deal with is likely to be wrong. The second is that the visual system is correct, but because the brain and other areas exceed the nervous system,

So it will reorganize itself and make up a new and correct story.

Naruto's words made Sasuke dizzy.

Although there were some courses in Ninja's world that involved science, they were not so stubborn.

Those who could calm down and study science were basically very important members of the laboratory.

Orochimaru, one of Konoha Sannin, was once a very good researcher.

"To put it simply, in addition to the visual system, there is also one of the most important information processors, the frontal lobe. The frontal lobe is a high-level thinking area, and it is the part of the brain responsible for prediction and decision-making."

"This also means that the visual analysis, calculation, and predictions in observation will all happen outside the visual system."

"In other words, the illusion I weaved is meticulous enough to deceive your brain, thus affecting your other senses to a certain extent." Naruto smiled. Under his control, the world in Sasuke's eyes rippled again.

"I can simulate the ripples produced by the wind fist in the air, and even the detailed changes caused by the surrounding flowers and plants. Through your eyes, I can build the scene I want in your brain sea. This can also affect your other senses to a certain extent. Is this explanation clear enough?"

"I understand, so this Kekkei genkai is called the fake Genjutsu Kekkei genkai." Sasuke suddenly realized.

"That's more or less the truth, so closing your eyes can really restrain my Kekkei Genkai well." Naruto nodded. "But most of Ninja relies on his eyes."

"Then let's use Sharingan." Sasuke's eyes turned into Sharingan's.

With the appearance of Sharingan, Sasuke's confidence began to swell. He covered his face and laughed wildly, "I saw it, I saw it again! I saw the illusion you weaved."

"I don't have the illusion now," Naruto said gently.

"Uh." The air was silent.

"This is not important. Use Kyōka Suigetsu quickly. Naruto, I want to use my eyes to defeat you!" Sasuke laughed wildly.

"As you wish." Naruto waved Kyōka Suigetsu and began to change the surrounding environment.

Kakashi, who was watching the battle from the sidelines, was also focused on everything.

Kyōka Suigetsu's real ability was to control the five senses, but it was also easy to control a single vision.

In order to test whether Kyōka Suigetsu's visual control was effective on Sharingan, and also to show the details of his ability to the higher-ups of Konoha, Naruto chose to fight with Sasuke this time.

When the illusion was finished, Naruto lightly hit Sasuke with a palm.

Sasuke's Sharingan crazily circulated, and Chakra gathered in his eyes, with surprise in his eyes.

"I saw it." Sasuke turned his body sideways to avoid Naruto's attack and punched Naruto in the face.

"Tomoe's Sharingan can break the visual control that he has not used his full strength." Naruto felt a chill in his heart and exchanged a few moves with Sasuke.

A look of exhaustion quickly appeared in Sasuke's eyes, and his breathing also became rapid. Chakra, who was in his body, was exhausted.

"Looks like it's the limit." Naruto forcefully shook off Sasuke's arms and retreated out of the battlefield.

"That's it."

"It's not over yet." Sasuke held his knees and panted heavily, his face full of unwillingness. "I can still fight."

"You have already done very well." Naruto shook his head.

Kyōka Suigetsu already had a certain understanding of his ability after this experiment.

As long as Naruto used all of Reiatsu, Kyōka Suigetsu would be able to block Sasuke who had 2 Tomoe.

One had to know that Uchiha's Genjutsu resistance was very high.

As long as Naruto's Reiatsu had a significant increase in strength, Kyōka Suigetsu, who was fully activated, would be unable to resist even 3 Tomoe.
